A balloon filled with ideal Helium gas (a monatomic gas) is tethered outside, and over time the balloon contracts from a volume of 1.15×10^3 m^3 to a volume of 1.05×10^3 m^3 . Assume that as it is contracting, the balloon maintains a constant pressure of 1.00 atm ( 1.013×10^5 Pa). The balloon contains 50,000 moles of Helium gas. Sketch a PV diagram for this process below. Label the pressures and volumes relevant at the initial and final times. Find the work done by the environment on the gas during this process. Did energy enter or leave the system as work? Find the amount of heat transfer to or from the environment during this process. Was the environment (outside atmosphere) at a higher or lower temperature than the helium gas during the contraction? Explain.
